- ** testll.c -- test suite for 64bit integer (longlong) operations
- **
- ** Summary: testll [-d] | [-h]
- **
- ** Where:
- ** -d set debug mode on; displays individual test failures
- ** -v verbose mode; displays progress in test, plus -d
- ** -h gives usage message.
- **
- ** Description:
- ** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
- **
- ** Successive tests begin to depend on other LL functions working
- ** correctly. So, ... Do not change the order of the tests as run
- ** from main().
- **
- ** Caveats:
- ** Do not even begin to think that this is an exhaustive test!
- **
- ** These tests try a little of everything, but not all boundary
- ** conditions and limits are tested.
- ** You want better coverage? ... Add it.
- **

- ** Author: Lawrence Hardiman <larryh@netscape.com>.

- ** Revision History:
- ** 01-Oct-1997. Original implementation.
